Final answer:
The concentrations of the four possible phosphate species can be affected by various factors, including pH and temperature.
Step-by-step explanation:
The concentrations of the four possible phosphate species can be affected by various factors, including pH and temperature.
At pH 7.00 and 25°C, the concentrations of Ca²+ and PO4³- ions in equilibrium with solid calcium phosphate are very low. However, the concentrations of these ions can increase at higher temperatures or with changes in pH.
It is important to note that the concentrations of phosphate species can also vary in different environments, such as in detergent formulations or in natural systems like the ocean.
